Application filed May 2, 1887, Serial No. 236,868. (MocleL) T0 all whom it may concern:

Be itknown that I, FRANK E. YOUNG, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new 'and useful Improvements in Combination-Locks and l do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, makinga part of this specification, and to the letters and figures of reference marked thereon, in which- Figure 1 is a perspective view of the lock proper. Fig. 2 is a detached view of a portion of the spindle, showing the key Web or blade attachedthereto. v Fig. 3 is afront side elevation showing the disk-shutter removed.

Fig. 9 is a perspective view of stop-Washer. Fig. 10 is a detached perspective view of one of the loose wheels. Fig. 11 is a detached perspective view of the cylinder and fixed wheel.

The present invention has relation to combination-locks designed and calculated to be used upon doors, safes, and bureaus; and its nature consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, A represents the case or shell, which may be substantially of the form shown in the drawings, reference being had to the purpose for which it is designed to be used. The face-plate a is formed separate and securely attached to the case A, and is provided with an aperture for the passage of the bolt. The case A is provided with apertures for the passage of screws to attach the lock proper'to a door or the place it is to occupy. The opening Bin the case A is closed with the disk-shutter b. Said 'shutter is provided with ,the hooked notches b', which engage the screws 292. The sliding bolt O is located in the top or upper portion of the case A, and is provided with the longitudinal slot c, which is for the purpose of receivingV o the spring c', said spring being for the purpose of actuating the bolt C. To the bolt O is pivotally attached the yoke D, said yoke being provided With the projections or lugs d, Which projections or lugs are for the purpose of engaging the hooked extremities d', located on the dog (22.

For the purpose of placing the bolt-spindle E close to the rear edge of the case A, the hooked extremities cl' are so shaped that they willbe located forward of the bolt-spindle, whereby the hooked extremities will give the bolt O a longer reciprocating motion. The yoke D and the bolt O are pivotallyconnected for the purpose of allowing either one of the hooked extremities d' to throw the bolt back while the other extremity passes or moves to the opposite direction whenthe dog d2 is operated by the spindle-knob. v

The bolt O is provided with the lug 02, which is for the purpose of engaging the detent F and lockingthe bolt C. The detentF is provided with the spring e, which is for the purpose of actuating said detent.

For the purpose of looking the detent F in a given or fiXed position, the sliding bar f is provided, which engages the lug f' on the detent F, said sliding bar f being held in a given or fixed position by means of the spring fz, engaging the notches fa, said bar f being operated by the knob g.

The rotary sliding spindle G is provided with the web or blade g', which is rigidly attached to said spindle G, and is provided with the notches or rec-esses 1 and 2, Which are for the purpose of engaging the spring h' and holding said spindle'stationary in the cylinder I'I, the spring h' being so adj usted that the spindle G can be forced back and forth, so as to engage with the desired notch or recess in the web or blade g'. The web or blade is also provided with the stop 71,2, Which is for thepurpose of limiting the outward movement of the sliding spindle G, the inward movement being limitedl by the inner end of the bit or blade abntting against the disk-shutter b. Y

The cylinder H is substantially of the form shown in Fig. 11, and is provided with the wheel I-l', which i-s preferably formed integral therewith. Said cylinder is located on the sliding spindle G, as shown in Fig. 4, and is Ico provided With a cleft or slot I, which is for the purpose of allowing the web or blade g' to slide endwise in the cylinder.

To the cylinder II is attached the spring YL', said spring bein g located substantia-lly as shown in Fig. 11, and is held in proper position by means of the groove 713.

The fixed wheel H' is provided upon its periphery with the master-notch I', and also the eounting-notches 12, said eountin g-notches being for the purpose of transmitting to the hand of the operator an intermitting sensation, so as to count the combination. The' cylinder II is also provided With the eollar or sleeve J, which is for the purpose of providing a bearing for the wheels K, said wheels being located substantially as shown in Fig. 4.

The loose wheels K are substantially of the form shown in Fig. 10, and are provided With the fiange K', said flan ge being provided With the notches K2, the number of 'said notehes corresponding with the number of notches I2 on the periphery of the fixed wheel II'. The wheels K are also provided with the radiating notches K3, which correspond in number and position With the notches K2, said radiating notehes being for the purpose of receiving the web or blade g' and cause the Wheel to 'rotate with the spindle G.

The wheels K are each provided with a central aperture for the purpose of receiving the cylinder H, through which cylinder the spindle G passes. The notehes K:l radiate fro'm the center aperture toward and on a line with the notches I72 in the flange of the wheels K.

The stop-Washer 7.: is substantially of the form shown in Figs. S and 9, and is so formed that when placed in the wheel K it is free to slide, so as to protrudeor retract the pin k', said stop-Washer 7o being laterall'y held in position by means of the flange K' The stop-Washer is also provided with the cam kg and pin ki, which are for the purposes hereinafter described. i

The frietion-plate L may be substantially of the' form shown in Fig. 7, and, as shown, is provided With the pi11sZ,wliich are for the purpose of entering the eleft or slot in the posts l' of the case A, and thereby preventing said frietion-plate from rotating. The frietion plate L is also provided with the notch or recess Zi, which is for the purpose of permitting the detent F to operate, as hereinaftcr described.

The Operations of my invention are as follows: To change or set the combination, the serews 112 are loosencd, and the disk-shnttcr rotated until it is disengaged from said serews, when, together with the sliding spindle G, cylinder H, Wheels Il' and K, the stop-wasliers and friction-plate L are WithdraWn from the lock-case A inwardly until the knob M comes in contact with the outside of the door. The pins 7a' are then placed in the desired notchcs in the flanges of the wheels K. The parts above mentioned are then replaced in the *by rotating the spindle-knob.

` Strikes the detent F.

case A, as shown in Fig. 4, and the diskshutter b fastened by means of the screws 112.

For the purpose of holding the detent F up out of the way while changing the combination and replacing different parts in the case A, as above described, the sliding bar f is pushed back until it engages the lug f' said detent beingr first elevated to its highest point Then the parts are replaced, the sliding bar f is withdrawn and the detent F allowed to descend and. rest upon the periphery of the wheels H' and K K, and the spindle G pushed or pulled .outwardly until the stop 7t2 comes in cont-act With the spring h'. The spindle G and cylinder II can then be rotated in either direction independent of the wheels K. The spindle G is pushed or pulled inwardly until the spring h' engages the notch or recess l in the web or blade g', said web or blade being then in proper position to strike the cam kz of the stop-Washer 7.: and protrude the stop pin k' and engage the pin 7.33, thereby communicating rotary motion to the first wheel K until the stop-pin Strikes the detent F. Then the spindle G is rotated in the opposite direction, the operator eounting off the number corresponding to the number of the notch in the wheel K, in Which the stop-pin h' is placed. The Counting isdone by ineans of the intermittent Sensation communieated to the hand of the operator by means of the detent dropping into the notches 12, formed in the fixed Wheel II'. It will be understood that pi ns may be used in place of the notches 12, if desired. It will be seen that if the proper number of notehes have been counted and the spindlc pushed or pulled inwardlythe web or blade g' will enter the radating notch corresponding to the master-notch m on the first wheel K, and the master-notches on the wheels K and H' will be in register and rotate together in either direction. Then the spindle G has been pulled or pushed inwardly until the spring h' engages notch 2 of the Web or blade g', the end of the Web or blade Will be in proper position to strike the cam h2 and protrude the stop-pin k' of the stop-Washer located in the second wheel K and engage the pin R3, thereby coinmunicating rotary motion to the second wheel K until the stop-pin The spindle G is then rotated in the opposite direction, the operator Counting off the number corresponding to the number of the notch in the second wheel K, in which the stop-pin k is placed. This brings the master-notch of the second Wheel K in register with the master-notch of the fixed Wheel Il' and the first loose Wheel K. The spindle G is pushed or pulled inwardly and the wheels all rotate together with the spindle in either direction. The masternotehes I' and m, all being in register, the spindle G is rotated until the detent F drops into said master-notches, thereby releasing the sliding bolt O.

When it is desired to use the lock as a catch IOO IIO

or day-lock only, the detent F is'fastened down by means'of the sliding bar f and lug To lock the door on the combinations, the spindle is first slightly rotated and at the same time pushed or pulled outwardly.

It Will be understood that the number of` Wheels K and their different parts may be increased, if desired.

It Will be seen that the pin of the stop- Washer 76 Will retract by the Weight of the Washer, and not engage With the detent F unless protruded by the Web or blade g'. In case the pin 7o' protrudes below, it Will not interfere With the'movements of the Wheels K, as there is nothing to come in contact with them;

The friction-plates L are for the purpose of holding the Wheels K in a given position, and not allowing them to-rotate except When the Web or blade g' comes in contact With the stop -Washer or radiating notches in said Wheels K. i

It Will be seen that the movements of the spindle G may be reversed by reve'rsing the stop-washers in the Wheels K.

The disk-shutter b fits in the circular opening B in the case A, and is provided With an overlapping flange 193.

The disk-shutter Z) is so adj usted that When placed in proper position it Will press against the adjacent loose'wheel K, and said Wheel against the adjacent friction-plate L, and said plate against the first loose Wheel K, and said loose wheel K against the next friction-plate. Said friction-plate presses against the fixed wheel H', Which prevents the loose Wheels K from rotating except When the Web or bla'de g' is engaged With thelwheels or Washers, as above described.

Having fully described my invention, What I claim as neW, and desire to secure by Letters Patent,'is-

1. The herein-described lock, consisting of the case A,'the disk-shutter b,'the bolt O, the

yoke D, the dog V672, bolt-spindle E, the detent F, sliding spindle G, cylinder H, provided IWith the' fixed Wheel'H' and spring 7L', the

Wheels K, stop-Washers 7a, and the friction- -G, having mounted thereon the cylinder H,
